Questions about 6.5 Coaxials in the Rear Deck

Has anyone replaced their HK or non-HK rear mids in the rear deck (not the 6x9)? Any cutting or dremeling involved?

I believe they are 6.25" and I'm trying to fit 6.5" MB Quart coaxials. Not sure about the depth or width.

Yes I put in 6.5 Kenwood Excelon coax to replace my stock H/K rear speakers. The tweeter stuck out a bit, so what I to recess them, was I used the carboard "baskets" that sit below the stock speakers. You know, the little enclosures. They sit down into a molded metal piece that makes them pretty secure. I essentially glued my speakers right to the top of these enclosures using hot glue. The speaker sits down into the enclosure, and then the top "ring" of the speaker is sitting on the top edge of the enclosure. I put a bead of blue all the way around the edge of the speaker ring where it met the cardboard. The resulting bond was very strong (I could pick up the enclosures upside down and the speakers didn't fall out). I then placed them back down in thier spots (they only sit one way because the thing they sit in is keyed), and its been very secure, with no problems 10k miles and counting. One thing though--make sure to hookup your speaker wiring first and run it out of the side of the enclosures before gluing if you decide to do this!

The factory grills easily fit in thier original spots with the speakers recessed this way and theres no indication of anything other then OEM. Looks perfect. Best of all, the gluing can all be done outside of the car (just take the enclosures out of the car completely to do the gluing them reinsert them with speaker attached when its dry).

Very cool, thanks for sharing your experience. So the only thing holding up the enclosure is strong glue? Any rattling when your speakers hit or vibrate?

Well the speaker is glued to the enclosure itself. That connection was very solid, as I could pick up the enclosure upside down and the speaker didn't fall out or move at all. The enclosure is only held into the car itself by gravity and the metal "key" or whatever you call it. There is a shape in the metal designed so it sits down in there. I haven't noticed any rattling whatsover from the speakers firing, or from the sub firing. This has the added benefit of protecting your speakers from bass waves interfering with the back of the speaker if you have a sub in the trunk. The mount to me seemed to be extremely solid.
